The thermal contraction of fifteen different neat-resin systems, on cooling from room temperature to 4 K, was measured with strain gages. Epoxy-, vinyl-ester-, polyester-, and cyanate-ester-based systems were studied. In general, the vinyl esters and polyesters contracted more than the epoxies during cool-down. Filled resin systems and tetrafunctional epoxy systems contracted less on cooling.This study represents the first time that the thermal contraction of these resin systems has been measured at low temperatures. The use of strain gages to measure thermal contraction at low temperatures has been shown to produce reliable data.
